Thisinvention relates to machines for use in the drying of macaroni,spaghetti, vermicelli and other materials originally in a plastic state,and has for its object, the provision of such a machine that is highlyetlicient in use and generally simple in its construction, and that willrapidly and thoroughly remove all moisture from the mateiials passedtherethrough.`

Furthermore, the invention aims to provide a machine of the foregoingcharacter wherein the moist material is passed therein from one floor ofthe building and after being dried, is forced to an upper floor andreceived in thoroughly dried condition in bins, boxes or other suitablecontainers. y

With the foregoing and other objects in view as the nature of theinvention will be better understood from the following specilication andaccompanying drawing, where- The figure is a detailed longitudinalsectional View through the entire device.

Now having particular reference to the drawing, the machine consists ofa suitable frame structure arranged in horizontal position upon onefloor of the building housing the apparatus. This frame preferably iscomprised of spaced vertical side bars 30 5 interconnected adjacenttheir upper and lower ends by longitudinally extending channel bars 6.Arranged longitudinally and on a horizontal plane within the upperportion of the frame structure is an air box 7 open at its top side andrear end. Arising from the bottom wall of the box at its front end is aperpendicular wall 8 that terminates beneath the open top of the box.|The rear end of this box 7 terminates in spaced relation with the rearend of the frame structure, whileassociated with the frame structure atsaid rear end of the air box is a suitable blower 9, the outlet mouthl() of which communicates with the adjacent end of the air box at apoint below the open top l thereof. The intake opening or openings ofthis blower is or are preferably located adjacent the building furnaceroom or any suitable source of warm or hot air supply so'v thatl'vs'farinair willi be the fair` box.

-Located within the open top'of the 7 Vabove said perpendicular wall 8andthe outlet mouth 10 of the blower 9 is a shakerV screen ll, whichpreferably consists` of a pair of side channel bars12412,',that`fsupport al,

during the operationof the power plant, the rotation'of theshaft 21 willcause therecipro- .cation of the connecting rods 20, and ingtuyr".

the ,arcuate motion of its connectedshaft V16, thus bringing about theshaking action of the screenlL* V, jV j 1 In order that the air from theblovveifft).V will be distributed in substantially uniform, mannerthroughout the :entire Ilength ofthe screen 1l,.there is located withinthe air box 7 beneath said screen, fourA air deflector boards 23.These-boardsmay be hinged orl laid loosely at their inner ends uponthe-bottom Wall of the airl box 7 adjacent theblower Y 9. The oppositeend vof each delectoris' equipped with anysuitable means such *as thatindicated* by the reference character 24,

whereby the inclination of the board towards1 the outlet end of theshaker screen may I`be properly` regulated to bring about the uni-j formpassageofthe air ,through the screen, and consequently, through themacaroni" or other material thereon. L f i AtA the outletfend ofy the'shaker screen 1l is afreceiving'jmouth Q5', vthe rear wall of which isinclinedandf extends into fa 'trough f 26, communicating with the lowerend of saidl niiz'uth.` Furthermore',v therej is located "withvinthetrou'gh and directly beneath the vinclined rear wall of said mouth,an inclined clined wall prior to its passage through said bailie plate27, the forward end of which teropening. l Y n minates in slight spacedrelation with the In testimony whereofY we ailix our signaforward wallof said trough. The lower open tures.

5 end of this trough 26 communicateswith a FRANCESCO PATRONO. [Ls] '70 iconveyor pipe 28 while communicating therei VINCENZO DI BARI. [1.. s.]

with at its inner end is a blower 29,- This pipe g y Y 28 extendsvertically through one or more iloors of the building and incommunication n n l with the extreme upper end thereof is a dried f' f vf f 75 materialreceiverBO. This receiver 30 is loy cated on a verticalplane, and is preferably in the form of a cylinder having an outletopening at its upper end and a material discharge v mouth 31 at itslower end. The pipe 28 comn y 80 municates with this receiver adjacentits upper end, so thatthe macaroni will be caught in the receiver, and aconsiderable proportion of the air will pass through the opening n atthe upper end thereof. Adjacent the botp n Y p p 8 5 tom of the receiverthere is provided a plu- Y Y rality of wire screened openings 32, sothat the air that has not escaped through the upper en'd of the receiverwill pass therethrough. i If desired, a suitablecontrol' valve 33 may be9-0 located within the discharge end of the receiver, and obviously, thedried material discharged is caught within suitable bins, boxes or thelike. Y v v 30. Suitable means is provided between said Y j? 9,5, powershaft 2l and the shafts of the blades of the blowers 9 and 29 whereby tocause the simultaneous operation of the blowers and the shaker screen.Furthermore, any suitable Y Y K A meanssuch as 34 may be provided forcaus- 109 ing the flow of the material to be dried onto the screen ll ata point adjacent the ymain blower 9.

In view of the foregoing description when Y K 40 considered inlconjunction with the accom- Y 195 panying drawings, it will be apparentthat we have provided a novel, simple and efficient apparatus for thedrying of macaroni and similar materials, and even though we have Y v lherein shown and described the invention as c v 1.1.0

consisting of certain detailed structural elements, it is neverthelessto be understood that some changes may be made therein without aifectingvthe spirit and scope of the appended 5 claim. 115

' Having thus described'our invention, what we claim as new and desireto secure by Letters Patent, is: In a machine of the class described, aconveyor pipe, a blower at one end of said conveyor pipe, a hopperhaving opposed downwardlygand inwardly inclined side walls and openinginto said conveyor pipe, and overn v p 6o lapping upper and lowerinclined baille plates V p f f Y l z, Y 125 in said hopper extendingfromthe 'sameiin- Y i clined Wall thereof to a point in spaced relation'to the opposite inclined wall to direct the gravitational flow ofmaterial deposited y Q5.- in said hopper onto the last mentioned kinl pY L i 13o i
